Random matrices have fascinated mathematicians and physicists since they were first introduced in mathe- matical statistics by Wishart in 1928. After a slow start‚ the subject gained prominence when Wigner introduced the concept of statistical distribution of nuclear energy levels in 1950. Since then‚ random matrix theory has matured into a field with applications in many branches of physics and mathematics‚ and nowadays random matrices find applications in fields as diverse as the Riemann

Older people who took part in a structured programme of Tai Chi found that their balance and physical strength improved‚ reducing the risk of falls‚ according to a paper in the latest Journal of Advanced Nursing. Researchers studied a group of fall-prone adults‚ with an average age of 78‚ living in residential care. 29 undertook a 12-week Tai Chi course three times a week and 30 formed the non-exercise control group. They found that the physical fitness of the exercise group showed significant
